You can simply print the hashCode of your HashSet by calling hashCode() function

 System.out.println("HashCode value: "+ set.hashCode());

Here set is your HashSet which has a function hashCode which is called.

The hashCode() method of HashSet in Java is used to get the hashCode value for this instance of the HashSet. It returns an integer value which is the hashCode value for this instance of the HashSet.
